DCS500 Pin and Parameter list
A 41
REV.REF_HYST
Parameter of MOTOR_1_FIELD_OPTIONS-function block. ( S8/16 )
Used in field reversal function. Hysteresis for torque reference during field reversal. The
absolute value of torque reference must be bigger than REV.REF_HYST before the field
reversal can take place.
1319 FB_P: I2 SC: TORQ HL: 4000 LL: 0 D: 80 U: %
REV.FLUX_TD
Parameter of MOTOR_1_FIELD_OPTIONS-function block. ( S8/16 )
Time period during field reversal when field current and internal FLUX of the motor don’t
correspond to each other. The flag FIELD1_REV_ACK located in FEXC_STATUS
(11203) changes state after this time delay.
1320 FB_P: I2 SC: 1 HL: 20000 LL: 0 D: 0 U: ms
F1_CURR_MIN_TD
Parameter of MOTOR_1_FIELD_OPTIONS-function block. (S8/16 | S21.233)
This parameter defines the time the actual field current is allowed to be lower than the
threshold F1_CURR_GT_MIN_L (1305) without error signal F39 (NO FIELD ACK). As
long as the actual field current is higher than the threshold, the flag FIELD1_CURR_MIN_L
located in FEXC_STATUS (11203) is set.
